Hi Kevin,
I ran in your neck of the woods (literally) last Sunday.
We currently have a pair of 10x20 EZ Up tents, courtesy of some amazing parents that raised the money on their own and just donated them to the team a few years ago.
We can't fit a 10x20 on our buses and still keep the drivers happy, but we do have parents that volunteer to bring the tents to the meet for us. The parents usually come down to the school when they are dropping of their athletes/we are getting ready to leave before the meet. The kids help load up the tents (or walls, if needed). The parents follow us out, the kids unload the tents (like Madman suggests, ours are bungeed onto a hand truck), and set things up. We reverse the process to take them home, keeping the tents in a storeroom that is less than 8 ft. from where the kids get off the bus. Sometimes, parents will pick up a tent the night before, if it is convenient.
However...
Our
original tent - one that went 15 years for us, and is still useable to a large degree - is courtesy of a company out of Texas called Shade King.
Their prices are
way less than EZ Up, once you get past that 1990's website experience and the... unique... personality of the owner. They use steel tubes, so it's heavy (right around 120 lbs), but you could hit that thing with a bat and it would still hold up. They were a little limited on colors, and don't screen print themselves, but that's easy to work around - plenty of people can put a logo on that for a team.
Our boys team uses another company, Eurmax:

Their tent seems a little higher weight than ours, but again the cost is significantly less than what you see with EZ Up.
